How to install the transcoding tools on Debian 8 "Jessie"?

For using open source transcoding with VIMP you have to install the necessary transcoding tools (MPlayer, mencoder, FFmpeg, etc).

Edit sources for "apt"

Debian uses the packet manager "apt" to install software. We first have to add the needed sources (repositories):
 
(we recommend using "joe" to edit the file)

touch /etc/apt/sources.list.d/deb-multimedia.org.list
joe /etc/apt/sources.list.d/deb-multimedia.org.list

We add the following lines to the file debian-multimedia.org.list:

# Debian Multimedia Repository 
deb http://www.deb-multimedia.org jessie main non-free
deb ftp://ftp.deb-multimedia.org jessie main non-free

Then save the file (with joe, ctrl-k->ctrl-x) and install the keyring for the previously added repositories (if asked, enter "Y"):

apt-get update
apt-get install deb-multimedia-keyring
apt-get update

Now we have to install the tools:

apt-get install libimage-exiftool-perl ffmpeg

For an update to VIMP 3.2.0+ you have to install exiftool:

apt-get install libimage-exiftool-perl

For VIMP <= 3.1.9 MPlayer/mencoder is needed:

apt-get install mplayer mencoder

VIMP >=2.7 can use the included presets. If you use an older version, don´t forget to copy the FFmpeg presets to /usr/share/ffmpeg. You can download the presets here.

Note: Since VIMP 3.1.3 "Open Source HD transcoding" has been added to all VIMP editions. flvtool2 is not needed anymore.
